\\\\IIIIIIIIIII I UNI D STATES PATENT OFFICE Specification of Letters Patent. Application filed April-10, 1906. $eria1No. 254,671.

To all whom it may cancer-rt: j Be it known that I, J OHN W. ALLEN, a citizen of the United States,residing at'Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Jars and Covers, of-

' which the followin is a specification.

fruit, or vegetables maybe hermetically i seats on'both the ar and the cover had a lu- My invention re ates to improvements in ars and covers; and one of my ob ects 1s to provlde a package wherem preserved meats,

sealed and kept in good condition for a number'bf years in. anyclimate.

A further object is to arrange the seats of both the jar and the cover in such amanner that when the-package is closed under vacuum perfect joints will be formed, so that extraneous fastening devices, as clamps,springs, &c. need not be employedto retain the cover upon the jar. A

' Jar-closures have been made wherein the rality of faces or membersflat and angu ar, flat and curved, all curved, or all angular; but I'am not aware that a triple seat has been produced in which the central member is I concavo-convex and the side members angular (or flat and angular) and with the outer member in thejar always a V-shaped groove into which a pin can be inserted in order to open the jar by breaking the vacuum; Such is the construction I have produced.

Referring now to the accompanying drawings, which illustrate .my invention, Figure 1 represents a vertical sectional view of my irn proved package in a closed condition. Fig. 2 is a broken vertical section of same with the cover and gasket removed from the upper edge of the. jar. Fig. 3 is a broken vertical section showing the cover and thegasket removed from the jar, said cover being provided with a modified form of seat. F1 4 is a broken vertical section of same in a c osed position.

In carrying out my invention I employ a ar 1, flaring toward its upper open end 2, so that its contents maybe removed in one piece. The upper edge of said jar is provided with a triple seat comprising a centrally-disposed convex shoulder 3, communicating at its opposite sides with V-shaped grooves l.

5 designates a cover, preferably of the same diameter as the ar, so that it will not project beyond the latter, and thus occupy. valuable space when a numberof jars are packed for shipment. Cover 5 is provided with an annular depending flange 6, adapted to fit snugly within the upper end of the jar to prevent the cover from shifting when placed in position upon said jar. The mar- Patented Dec; 5, 1905..

ginal flange 7, formed between the periphery :of the cover and flange 6, is provided at its under side with a triple seat comprising a concave groove 8 and V -shaped shoulders 9, said groove and shoulders being adapted to register with the shoulder and grooves, respectively, of the jar, as shown. Cover 5 has a concave under side 10 for a purpose hereinafter specified. g

11 designates a gasket of resilient material adapted to be interposed between the jar and the cover in order to form air-tight joints between the seats of same. By providingthis gasket the seats need not be ground, as it will conform with and fill any slight cavities or inequalities which may exist in said seats.

When the above described ackage is closed under vacuum, cover 5 be drawn tightly into contact with the gasket, and

thus force the latter into contact with the seatson both the cover and the ar and also I into contact with the outer surface of flange thevacuum therein.

In the modification shown in Figs. 3 and 4 cover 5 is provided with an annular V- shaped shoulder 8 and flat seats 9*, disposed at opposite sides of said shoulder.

In practice I .prefer to construct the jar and the cover of glass to overcome the preju' dice now existing against canned condiments and so that the condition of the contents of the package may be observed and in order that said contents may present a palatable ap earance. When the contents consist of chipped beef or bacon, the rocess of packing the jar can be easily comp eted by p acing a dish of the beef or bacon in concave, 10, as this gives a finishedappearance to the package.- Although the cover will be reliably held upon ,the jar by the vacuum in the latter,

Ioo

said cover and the gasket may be readily re- 7 IIO be used an unlimited number of times for the same purpose.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A jar, a convex shoulder extending around the upper edge of said j ar, a cover provided with a concave groove adapted to register with said shoulder and angular seats on both the jar and the cover at both sides of the shoulder and groove respectively.

2. A jar, a triple seat extending around the upper edge of said jar, a cover, and a triple seat on said cover adapted to register with the seat on the jar, the central member of each triple seat being of different shape from its inner and outer members. 3. The combination of a jar, a triple seat extending around the upper edge of said jar, and having its central member curved and its side members angular, a cover, a triple seat on said cover adapted to register with the seat on the jar, and a resilient gasket adapted to be interposed between the seats of the jar and the cover.

4. The combination of a jar, flaring toward its open end, a triple seat extending around the upper edge of said jar, a cover, a triple seat on said cover adapted to register with the seat on the jar, the central member of each triple seat being of different shape from its inner and outer members and a resilient gasket adapted to be interposed between the seats of the jar and the cover.

5. A jar having two V-shaped grooves in its upper end, a convex shoulder communicating with said grooves, and a cover adapted to close'the open end of said ar.

6. The combination with a jar, of a cover adapted to close the open end of said ar provided with a concave groove, and V-shaped shoulders arranged at opposite sides of said grooves.

7. The combination with a jar, of a cover adapted to close the open end of said jar, and having a concave under side for the purpose set forth, a marginal flange formed integral with said cover and provided at its under surface with seats,- a flange depending from said cover adapted to fit snugly within the jar, and a resilient asket interposed between the upper edge of tlie jar and the seats of the cover.

8. The combination with a jar, triple seats on the upper edge of said jar, a cover, triple seats on said cover adapted to register with those on the jar, the central member of each triple seat being of difi'erent shape from its inner and outer members and a resilient gasket interposed between said seats, substantially as described.

9. The combination of a a1, triple seats at the upper edge of said jar comprising a cen tral convex shoulder and V-shaped grooves at opposite sides thereof, a cover, triple seats on said cover adapted to register with those on the jar and comprising a central concave groove and V-shaped shoulders at opposite sides thereof, and a resilient gasket interposed between said seats, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.

JOHN W. ALLEN.
